They are like $1/GB. One 23 minute episode has to be at least 175MB's to retain 95% quality, and 233MB/episode to retain 99% quality.
By looking at your stats of the two video's I would first suggest to reduce the frame rate to either 15fps or 24fps.
in Vdub->video->frame rate-> decimate by 2.
Direct stream copy this and see how it looks, if its too chopy then forget it do this:
Load the video into TMPEG
settings->advanced->inverse telecine
You should see 5 frames with frame 1 and 3 highlighted, this is fine. Save the project and load the .trp into VFAPI then load the VFAPI avi into vdub or ndub for encoding. This should effectivly create a 24fps avi. If this doens't work go back and select the first 4/5 frames and repeat, I forget which one works...or you can just buy a bigger HD.
Also if you REALLY REALLY want to decrease the quality that much, keep it at 22,050Khz, and create a mono wav. Then encode that at like 32Kbps, and you can still retain fair sound quality.

I already made my first good enc epi. I made it on feeling and the VD "Projected File Size" helping a bit.. The quality was pretty nice I got rid of some freeze frames and the size was satisfacting (64mb)

Just a small question for further enc, where/with what.. Can i see a files video and audio bitrate?

Open your video in VD and open File Information. The bitrate of the video, however, cannot be determined easily from there and a calculator will help you determine the bitrate better (You have the filesize and play length. You're only missing the bitrate. ).

brw I found out what was ****ing upp my brightness.. Sometimes i play CS and therefor I need HIGH brightness (and because of my crappy monitro I have to change it in WINDOWS) So VD must have used my prefrenceses av default and then added the (brightness of the original movie) making it alot darker than it should be...
